Description

Technical Field

[0001] The utility model relates to the technical field of plastic pipe production, in particular to an extruder for producing plastic pipes. Background Art

[0002] Plastic pipe is a tubular product made of plastic material. It has the advantages of light weight, corrosion resistance, high temperature resistance, high pressure resistance, smooth surface, easy installation and maintenance, etc. Therefore, it has been widely used in construction, water conservancy, chemical industry, electric power and other fields. An extruder is needed for the production and processing of plastic pipes. The "a kind of extruder for plastic pipe production" disclosed in the application number "CN218196807U" has solved the technical disadvantages of requiring other equipment to cooperate with the extruder, but in actual use, extruders with similar structures still have many defects. For example, the overall heating structure is relatively simple, and it does not have the function of heating the raw materials in different areas when in use. Therefore, when the heating mechanism of the extruder is operating at full power, it will increase the loss and waste of electric energy, resulting in an increase in the cost of plastic pipe production; at the same time, the function is relatively single, and it does not have the function of automatic mixing and quantitative feeding of different raw materials during operation, so it is necessary to design a plastic pipe production extruder.
